Operational amplifiers — or op amps, as you probably call them — have long been a key building block in analog circuits. It’s true even in our digital age as op amps are tapped to handle useful ...

Every single component within your vehicle relies on the battery to function correctly. But how do you know just how good of a battery you have? Easy! You familiarize yourself with the ampere-hour ...

Ampère was playing with wires when he discovered a fundamental law of electromagnetism. Hans Christian Oersted had just discovered the connection between electricity and magnetism. Meanwhile, a French ...

In designs using multiple LED strings such as brake lights, daytime running lights, rear lights and other automotive lighting applications, current-balancing circuits supply equal current to all LED ...

An op amp-based amplifier design overcomes errors associated with resistive current sensing, particularly those resulting from high commonmode voltages. Many current-sensing ICs are available for ...

Have you ever wondered how a car engine starts? Or how the air conditioner turns on when the car is switched off? The answer to these questions is simple: the battery plays an essential part in the ...

Insulated-gate bipolar transistors (IGBTs) require full protection to avoid damage and failures resulting from conditions such as short circuits, overloads and overvoltages. The protection is key to ...

A current flow for one hour measured in amperes (amps). Abbreviated "Ah" and commonly called "amp-hour," it is widely used to rate how long it takes for a battery to discharge. For smaller batteries, ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...
